Find my band size

No tape measure? A photo is enough. As an image has no scale, we use an object of known size — a bank card or your Apple Watch — as a ruler to estimate your wrist size and recommend the right size.

  1. 1

    Take a photo

    Your wrist with a bank card laid on it (or your Apple Watch) as a size reference.

  2. 2

    Place the two markers

    The blue line on the card (85.6 mm), the orange one across your wrist.

  3. 3

    Get your size

    We convert it into a circumference and recommend the S/M/L size suited to your band.

Take a photo of your wrist with a bank card laid flat against it (edge clearly visible). A card is exactly 85.6 mm long — that's our ruler.

Load a photo, then place the blue line on the reference and the orange one across your wrist.

Indicative estimate (± ~1 cm). If in doubt, measure your wrist with a tape measure and compare with the table above.

Which case size should you choose on the product page?

There are only two fittings. Small: cases of 38, 40 and 41 mm (Series 1 to 9, SE) and 42 mm on Series 10 and 11. Large: 42 mm on Series 1 to 3, 44, 45 and 46 mm, and 49 mm (Ultra). The 42 mm case exists in both families: your watch model decides.

When the product page offers the size for your model, choose it; otherwise, choose the one given after “otherwise”.
